COMBINED TABLEAND GUARD ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 701,824., dated June10, 1902.

Application filed December 26, 1901. Serial No. 87,174. (No model.)

To all whmn it may concern:

Be it known that I, ELLA H. AHRENS, a citi zen of the United States, anda resident of the city of Philadelphia, State of Pennsylvania, haveinvented certain new and useful Improvements in a Combined Table andGuard Attachment for Sewing-Machines, of which the following is a full,clear, and exact description, reference'being had to the accompanyingdrawings, forming part of this specification.

This invention relates to improvements in a combined table and guard foruse with sewing-machines, particularly those of the Willcox & Gibbstype, although it may be applied to any other type of machine to whichit is adapted.

The general nature of the invention consists in providing a plate whichmay form an extension of the machine-table and which at one end extendsupwardly and around the machine-arm, so as to prevent the material beingoperated upon from coming in contact with oil, dust, and irregularworking parts of the machine. way whereby the material, especially whenin long and heavy pieces, is allowed to pass more easily under themachine-arm.

For a full and complete disclosure of this invention reference may behad to the following description and the accompanying drawings, inwhich- Figure 1 shows a perspective view of my device applied to asewing-machine, and Fig. 2 is a perspective view of the device alone anddetached from the machine.

In the drawings,A represents a plate adapt ed to be attached to themachine-table by any well-known means, but in this instance is athumb-screw passing through the extension or car D and into the plateforming the machine-table. At the opposite end of the plate A from thatof the attaching means is a curved upwardly-extending shield or shell 0,which is adapted to closely surround the machinearm and cover theirregular and moving parts both below the surface of the table and backof the arm. This shield connects with the plate A by a reduced portionsubstantially semicircular in cross-section, which gradually flares intothe large portion G near the top.

Said plate also forms a guide-.

It will be noticed that the portion F where it meets the table forms agradual curved surface, obviating any small recesses for the collectingof dust, &c., and prevents the material passing under the arm frombecoming wedged or retarded in its movement. The shield, as shown, ispreferably integral with the plate and stamped from one piece of sheetmetal, although the operativeness of the de-- 6e vice is not dependentthereupon.

An apron or front downwardly-extending portion B is provided to permitthe work to more easily pass the edge of the plate and to keep the sameaway from the lower portions of the mechanism.

It will be noticed that by the construction described it is necessary toattach the device to the machine by one fastening only, the peculiarconstruction of the shield serving as a supporting part and also holdingthat end of the device in position. The simplicity, efficiency, and easeof manipulation establishes the increased advantage and utility of thisdevice.

Minor changes in details self-suggestive to one skilled in the art maybe made without departing from the spirit of my invention; but

What I claim as my invention, and desire So to protect by LettersPatent, is

1. A combined table and guard attachment .for sewing-machines,comprising a plate or table adapted to be attached to a fixed part ofthe machine, and an upwardly-extending shield having the form of asemiclosed figure in cross-section, secured to said table and adapted toinclose the machine-arm, substantially as described.

2. A combined table and guard attachment 0 for sewing machines,comprising a plate, adapted to overlap the machine-table, anupwardly-extending semitubular shield adapted to inclose themachine-arm, and means for attaching said plate to the machine t-able, 95 substantially as described. V

3. A combined table and guard attachment for sewing machines comprisinga plate adapted to be attached to the machine-table, anupwardly-extending shield having a semi- I60 circular curved, reducedlower portion anda flaring upper portion adapted to embrace the allyupwardly curving surface and reduced at its lower portion and flaredabove to embrace the machine-arm and means for attaching said plate to tthe machine, substantially as described.

In witness whereof I have hereunto set my hand this 16th day ofDecember, A. D. 1901.
